Shellfish samples were collected from the coastal cultivating areas of east Xiamen Island and Minjing Estuary, China and analyzed for hexachlorocyclohexanes (HCHs), DDTs and polychlorinated biphenyls (PCBs) by GC. Concentration ranges of HCHs, DDTs and PCBs in the coastal area of east Xiamen Island were 0.18-345, 75.2-2143 and ND-23 ng g(-1) dry wt., respectively; those for Minjiang Estuary were ND-5.07, 21.5-2396 and ND-6.78 ng g(-1) dry wt., respectively. The results showed that the organochlorines were evidently accumulated in marine bivalve molluscs, particularly in oyster. The concentrations of organocholorine pollutants in shellfish samples varied with the sampling locations, the season of collection and organism species, but were generally higher than those in the sediments. The concentrations of DDTs in the shellfish were high as compared with HCHs and PCBs, so that DDTs can be considered as the typical organochlorines in the survey areas. The residue levels and compositions of HCHs, DDTs and PCBs are discussed.
从中国厦门岛东部和闽江入海口的沿海养殖区采集贝类样本，并用气相色谱法分析其中的六氯环己烷（HCHs）、滴滴涕（DDTs）和多氯联苯（PCBs）。厦门岛东部沿海地区HCHs、DDTs和PCBs的浓度范围分别为0.18 - 345、75.2 - 2143和ND - 23 ng g(-1)干重；闽江入海口的浓度范围分别为ND - 5.07、21.5 - 2396和ND - 6.78 ng g(-1)干重。结果表明，有机氯明显在海洋双壳贝类中积累，尤其是在牡蛎中。贝类样本中有机氯污染物的浓度随采样地点、采集季节和生物种类而变化，但总体上高于沉积物中的浓度。与HCHs和PCBs相比，贝类中DDTs的浓度较高，因此DDTs可被视为调查区域内的典型有机氯。文中讨论了HCHs、DDTs和PCBs的残留水平及组成。
